矿用隔爆型高压总进和联络开关闭锁装置的研制与应用

Development and Application of Mine Flameproof High-voltage General Entry and Contact Switch Interlocking Device

为避免矿井供电系统两个不同母线段分列运行时联络开关误送电造成事故,现采用矿用隔爆型高压总进和联络开关闭锁装置,通过内部的电气闭锁回路能可靠地防止联络开关误操作。

In order to avoid the accident caused by the power switch contacts by mistake to turn on when two separate sub-paragraph bus of the mine power supply system works by tier, the interlocking device of mine flameproof high-voltage general entry and contact switch is adopted. The misoperation of the bus-tie switch is prevented reliably through the inner electrical latch circuit.
